title: [Arterial blood-gases and acid-base balance in acute diseases of the lower respiratory tract in infancy (author's transl)].
abstract: A group of 31 infants, aged 1 month to 13 months, recovered at the Pediatric Institute of the University of Florence for acute diseases of the lower respiratory tract, were analyzed for paCO2, paO2, pH and BE. Samples of arterial blood were obtained in the first, second, fourth and eighth day of recovery. Hypoxia occurred in all the infants and metabolic acidosis was found in almost every case. The paCO2 value resulted high in some of the babies, normal in others and below normal in the remaining. pH showed a lower value in patients affected with metabolic and respiratory acidosis. paCO2 returned to normal value on the eighth day in all the infants, while pH remained slightly below normal value, due to persisting metabolic acidosis. paO2 registered only a small increase during the stay, remaining on the eighth day still below normal level.
